Specification of Letters Patent.

Patented Dec. 16, 1913.,

Application filed July 22, 1939. Serial No. 509,039.

To all whom it may concern Be it known that I, FRANK. ll, Dyan, a citizen of the United States, and a resident of Mont-Clair, in the county of Essex and State of New Jersey, have made a certain new and useful Invention in Phonographs, of which the following is a description.

llily invention relates to phonographs, and the chief object thereof is to provide a phonograph reproducer whereby cylindrical sound records of different diameters may readily be brought into adjusted position to be engaged by a reproducer stylus.

When it is desired' to bring a cylindrical sound record of an external diameter dili'erent from that of a record for the reproduction of which the phonograph is adjusted into engagement with the reproditicinp; stylus, the desired end may be encompassed either by movement of the phonograph mandrel or re(':ord-carryin,g support into proper position for the co-action of the record carried thereby with the reproducer stylus, or, the phonograph mandrel being; stationary, the position of the neproducer may be adjusted so thatthe stylus carried thereby is brought into operative relation to the new record. In a companion application Serial No. 509,040 filed on even date herewith, I disclose means operatingby the last named principle, the mandrel having no movement toward and away from the reproducer, while the latter is carried by a sound conveying tube pivoted atsuch a point that the re nroducer stylus may be brought into operative relation with records of different diameters by pivotal movement 01" this tube. in the present application, the rcproducer held in fixed position, while the adjustment for different sizes of records is obtained by movement of the phonograph mandrel toward and away from the reproducer.

Having this object in mind, my invention consists in the construction of parts and combinations of elements necessary or desirable for the carrying out or the desired objects, all of which are more particularly described and pointed out in thewfollowing specification and appended claims.

Attention is hereby directed to'the accom- 'ianying drawings forming part of this specification, and in which-- Figure 1 represents an end elevation of a phonograph embodyin; my invention, the inclosing cabinet being shown in section; and Fig. 2 represents a top plan VlGW of the same, a record of large diameter being shown in cross section.

The same reference numerals are employed in both figures to denote corresponding parts.

deferring to the drawings, the driving shaft 1 carries pulley 2 which is driven from the motor by means of a belt in the well known fashion. l/Vhile it is-obvious that within the spirit of my invention. the progressivc feed of the reproducer relative to the record may be obtained either by movement ofthe reproducer past the axially immovable record'or by axial movement of therecord past a stationary reproducer, I have illustrated in the drawings a form in which the rcproducer is stationary, the feed being obtained by axial movement of the record. To encompass this result the phonograph mandrel, its supporting means, the feed screw, and the means for rotating the mandrel and feed screw are carried by the traveling carriage 3 which is slidably mounted upon guide rods 4;, 5 supported in brackets G, 7 rising from bed plate 8. Motor 9 is supported. from the under side of bed plate 8 in any convenient manner, a spring); suspension 10, as illustratedin the drawings, being preferable. Reproduce/1' 11, which is provided with the usual diahragm, stylus, and other necessary parts, is supported upon the end of: soundconvey' ing and amplifying tube 12, reproducer 11 preferably being" supported in a vertical po sition, the end of tube 12 being connected with the neck oi the reproducer. Preferably, the tube 12 extends rearwardly from reprodpeer 11, thence downwardly through the cover 13 of the cabinet Li, and thence forwardly within the said cabinet beneath motor 9 to its mouth within. the "trout member of cabinet 14.

Bed plate 8 of the phonograph is mount ed for movement toward and away from rpproducer 11. This result is preferably attained by the employment; of rollers 15 which are mouhted on studs 16 within openings in the top 13 of cabinet l l. The machine isada'pted to operate upon records of different diameters, as the large record 17 illustrated in full lines in Fig. l of the drawings, and the small record 18 illustrated in dotted lines in said figure. As illustrated, the parts are in proper position for the operation of the reproducer stylus upon the large record 17. In this position, bed plate 8 has been moved forwardly, as illustrated in Fig. 1 of the drawings, until lugs 19 carried by bed-plate 8 have con tacted adjustable stop screws 20 carried by lugs 21 upon the top 13 of the cabinet. \Vhen it is desired to operate upon a small record as 18, which has been substituted for the large record, the bed-plate 8 is moved rearwardly upon rollers 15 until lugs 22 upon the rear of plate 8 contact adjusting screws 23 mounted in brackets 24: upon the top 13 of the cabinet. The bed-plate 8 may be retained, if desired, in either adjusted position by any convenient retaining means. It is obvious that the construction will be equivalent if movable bed-plate 8 were given a vertical movement of adjustment instead of one in a horizontal plane, the reproducer 11 then being supported horizontally above the axis of the mandrel. Such a construction will be seen by considering the left hand side of Fig. 1 of the drawings to be the bottom, the amplifying or mouth,

portion 25 of sound conveyor 12 in this case. of course, being bent through an angle of 90 degrees from its position shown in the drawings, so that the sound would be delivered through the front wall of the cabinet instead of through the bottom. Insuch,

a construction, retaining means for securing movable carriage 8 in its adjusted positions would be necessary.

As illustrated in the drawings, reproducer 11 is provided with a weight or stylus support 26,,th'e spring 27 being relied upon to -hold the stylus (not shown) in operative position relative to the record. In the construction of the movably adjustable c'arriage in which the reproducer is directly above the axisof the mandrel, a floating weight. could be employed without the aid of a spring, gravity'being sufficient to keep the stylus in operative relation to the record As illustrated in the drawings, the man drel 28 is fixedly mounted upon sleeve 29 which is supported rotatably within the 7 standards of traveling carriage 3 mounted upon guide rods 4, 5. Driving shaft 1 extends within sleeve 29. which sleeve is provided internally with a key way which is engaged by the key 30 upon the end of shaft 1. Feed screw 31 is carried by traveling carriage 3 and co-acts with feed nut 32 which is carried by the usual spring support 33, the latter being mounted upon lever 34 pivotally mounted at 35 carried by bracket 36 rising fromthe adjust-able plate 8. The chain'of gears 37. 38, 39 connect sleeve 29 with the shaft of feed screw 31,

--illustrated at 18.

rotation of pulley 2 thus resulting in the rotation of the mandrel and the feed screw and the consequent progression of carriage 3 axiallyof the mandrel, feed screw 31 rotating within stationary nut 32. As the traveling carriage progresses, the sleeve 29 moves along driving shaft 1, which extends farther and farther within the bore of mandrel 28. It is, of course,-obvious thatplace of this construction I might equall well employ a construction such as that illustrated in the application of Frank D.

Lewis, Serial No. 473,536, for improvements in phonographs, filed January 21, 1909. In such a construction, the driving shaft is firmly fixed to the rotating mandrel and advances therewith, the shaft being.

provided with a key way in which a set screw or equivalent device in the driving pulley engages, the pulley being held against axial movement.

The mandrel 28 is adapted for the reception of a record of small-size, such as that When it is desired to operateupon a record of large size, as illustrated at 17, it is necessary to place a false mandrel of larger diameter upon mandrel 28. Such a false mandrel is shown at 10. Mandrel 40 is provided with aninner tube preferably of spring metal 41, which may be elastically supported upon mandrel 28. At its inner-end mandrel 40 may be provided with a short similar tube 42 mounted upon the inner end of mandrel 28. It is obvious that, if desired, tubes 41 and 42 might be replacedby a single tube, It will be noticed that sleeve 29 extends beyond the outer end of mandrel 28 a suitable distance so that the key 30 upon the end of driving shaft 1 may be provided with a driving key way throughout the entire travel of a record of large size.

Suitable means may be provided. for removing feed nut 32 from operative engagement with feed screw 31 when it is desired to change the record. As illustrated in the drawings, I have mounted feed nut 32 upon' lever 34; which may be provided with a suitable end as 43 for manipulating the same, although other suitable means may be employed for this purpose. It is to be noted that as motor 9 is carried by the adjustable bed-plate 8 upon which the pulley 2 is also supported, the distance between the centers on the motor shaft and the driving shaft re mains constant.

Having now described my invention, what I claim and desire to protect by Letters Patout is as follows:
